Oops, more Mad cow here in Canada!

An Alberta dairy cow does indeed have mad cow disease, the Canadian Food Inspection Agency is reporting.

That makes the cow the second animal found in Canada with Bovine Spongiform Encephalopathy (BSE) since May 2003.

At that time, a cow on a northwest Alberta ranch was found to be infected with BSE, leading to a crisis for Canadian beef producers as the United States and other customers banned the importation of beef or live cattle from this country.

The federal agency said Sunday in a news release the animal in question hadn't entered the human or animal food chain and there was no increased risk to the public.

Certain parts of cattle such as the brain and spinal cord are known as specified risk material (SRM), the release said.

"Canada requires the removal of specified risk material (SRM) from all animals entering the human food supply. ... This measure is internationally recognized as the most effective means to protect public health from BSE."

Despite the finding, the United States has said it still plans to open its border to live cattle by sometime in March.

"We don't anticipate it would have any impact," U.S. Department of Agriculture spokeswoman Alisa Harrison said Thursday after news came out about the new suspected case.

It said Canada is considered a minimal risk region and that it was anticipated additional BSE cases could appear when considering whether to resume live cattle trade.

The U.S. currently accepts boneless cuts of beef from young Canadian cattle.

The CFIA said the new positive case is a eight-year-old cow that was a 'downer,' meaning it was unable to walk.

It noted the animal was found using the national surveillance system, which tested 22,000 cattle in 2004.

The infected cow's original farm has been found. The investigation will shift to finding cattle of similar age from that farm and any offspring from the infected cow.

"The Agency has also launched a feed investigation to examine what the infected animal was fed early in its life, when infection was most likely to have occurred prior to the 1997 feed ban," it said.

Older cattle could have eaten contaminated feed. Canada and the U.S. established rules in 1997 prohibiting the feeding of animal protein to cattle and other ruminant animals to prevent the spread of BSE.

That was identified as a transmission mechanism during a mid-1990s BSE outbreak in the United Kingdom.

The 19-month BSE crisis has taken an economic toll on Canadian beef producers. They estimate their industry has lost more than $4 billion and 4,200 jobs since it began.
